+        Starting with version 2.0 of the library, the minimal version of the Java
+        platform required to compile and use commons-math is Java 5. This version
+        is widely deployed now on many systems. It brings new important features
+        for specific mathematical developments, for example new functions (log10,
+        cbrt, ulp, signum, cosh, sinh, tanh, hypot, expm1, log1p), autoboxing,
+        MathContext or RoundingMode. It also brings important features for general
